CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 570,286, dated October 27, 1896.

Application filed May 14, 1896- Serial No. 591,513. (No model.)

description, reference being had to the accompanying drawings, forming part of this speciflcation, in which- Figure 1 is a side elevation of my improved truck, the left-hand half being broken away to show the inner face of the opposite side Fig. 2 is a top plan View of one-half v of the truck. Fig. 3 is a cross-section on the frame.

line III III of Fig. 1, and Fig. 4 is a cross-section of the bolster and the spring-channel and their connections. of the side frame, showing the supportingsprings.

My invention relates to the construction of the trucks employed upon either railwaycoaches or street-cars, and is designed to provide a truck of simple design which shall be composed entirely of rolled shapes and give a strong and effective construction.

In the drawings, in which similar numerals indicate corresponding parts, 2 represents the center web-plate of the side frame, this plate having riveted at its top and bottom edges parallel angles 3 3, arranged in pairs, the upper angles extending over the journal-boxes. To the lower face of the upper angles are riveted angular chafing-strips 4 4, which rest upon the ends of the semielliptical springs 5 5, there being two of these springs over each journal-box, as shown, instead of the ordinary single spring heretofore employed. The central portion of each web-plate is cut away to admit the projecting of the bolster-springs therethrough. Upon the inner side of each side frame, above the bottom angle-iron, is riveted a horizontal angle-iron 6, which partly supports the transom-channels, the flanges of which are riveted to the inwardly-projecting flange of the angle-iron. These transomchannels are also fastened to the side frames by means of vertically-extending angles 7 7, which are riveted to the transom-channels and to the Web-plates of the side frames. The

Fig. 5 is a sectional view upper flanges of these transom-channels are secured to the side frames by the gussetplates 8 8, which are riveted to the top flanges of the channels and to the two top angles of the side frames, thus giving a very secure and durable connection between the side frames;

Near the ends of the transom-channels I rivet to theirinner faces two bent plates 9 9, through which and through the webs of the channels are drilled suitable holes for the reception of pins 10, from the intermediate portion of which pins depend the hanger-bars 11, which support the horizontal spring-channel 12 by means of pins 13 passing'through its flanges, as shown. .By means of these bent plates, which are riveted to the inner faces of the channels, the hanger-pins are put in double shear, thus giving a very secure connection for transferring strain from the spring-channel to the transom-channels.

In addition to the transom connections above describedI secure at each end of the transom two angles 14: 1 1, one for each channel, riveted to its back or inner side, these angles serving to limit the side motion of the swingin g bolster. The web-plates of the side frames are cut away above the journal-boxes, as indicated by dotted lines, a suflicient distance to allow deflection of the semielliptical springs, and to the web-plate on each side of the journal-boxes are riveted suitable angles 15, which slide in thevertical guides of the journal-boxes. To the inner flanges of these angles are riveted plates 15, which serve as wearing strips, the securing-rivets being countersunk on the wearing side.

Near each end of the web-plate the portions on each side of the recess for the journal-box are firmly held together by means of a tie-bar 16, which is bolted between the flanges of the angle-irons on each side of the journal-boxes, thus giving a rigidly-tied side frame. If desired, those portions of the Webs on either side of the journal-box and forming the continuation of the central web of the side frame can be made separate from the central web, as shown by dotted lines in Fig. 1, these being attached to the top angles of the side frame by means of a bolt or pin 17,

which acts as a hinge, so that if the bolts of the tie-plate are removed the ends of the side frames can be swung up out of the way and the wheels and axles removed endwise, the truck being lifted sufficiently to relieve the semielliptical springs of their weight.

The bolster of the truck consists of a rolled channel-iron 20, with the flanges extending upwardly, so that the same may be easily riveted to the two side plates 19, which form the tension members. These sideplates are suitably cut away at their ends, as shown in Fig. 3, and, if desired, the channel may be reinforced by two transverse angle-irons 20, riveted to its under side, thus distributing the load transmitted from the center plate 21. This center plate may be riveted directly to the web of the channel or may be set on the top of an intermediate plate 22, as shown, both being riveted to the web of the channel. The side plates of the bolster may be rein forced at their center by means of a short channelseetion t3, riveted with the flanges extending downwardly, as shown. Near the ends of the bolster and on the upper face of the channel-web are riveted Z-bars 24:, arranged in pairs, these Z-bars having a top plate 25, riveted to the top flanges, the heads of the rivets being countersunk, thus forming chafingbloeks for the bolster. These z bars are preferably secured by rivets passing through two plates 26, which are placed 011 the lower face of the channel, and are spaced apart a sufficient distance to admit between them the central portion of the elliptical bolster-sprin g, which bears upon the lower face of the channel, as shown. This construction not only provides chafing-blocks, but also assists materially in stiffening the channel of the bolster at this point. The spring-channel 12 is preferably reinforced on each side of the pins 13 by the two angle-irons 27, placed on either side of the pin and riveted through the web of the channel and through supplemental plates 28, placed on the upper face of the channel and spaced apart a sufficient distance to receive the central portion of the elliptical bolster-sprin The holes in the spring-channel for the pins are preferably drilled close to the web, so that the pin may bear upon the web.

. The advantages of my invention will be apparent to those skilled in the art, since a passenger-truck is provided which is built up entirely of rolled shapes that may be bought in open market, while a strong, simple, and effective construction is obtained. The construction shown may be employed with a sixwheeled truck, if desired.

The channel of the bolster may be employed with the flanges turned up or down, as desired, or it may be composed of an I- beam with two web or side plates, and the construction and arrangement of the parts may be varied in many other ways, which will readily suggest themselves to those skilled in the art, without departing from my inven- 'tion.
